Radar observations of comet Hyakutake (C/1996 B2) made at the Goldstone Deep Space Communications Complex in California have detected echoes from the nucleus and from large grains in the inner coma. The nucleus of this bright comet was estimated to b

Arecibo 12.6-cm delay-Doppler measurements are used to study the topography and radar scattering properties of the Chryse region, including the Viking 1 and Mars Pathfinder lander sites and environs. The Viking 1 lander lies on a gentle (0.13°) east

A wide variety of aspects of Mars radar scattering are examined. The spatial variations and wavelength dependence of the echo were investigated from dual-polarization continuous-wave radar observations of Mars from the 1988 and 1990 oppositions. The

Solar wind velocities measured by earth-orbiting spacecraft are compared with velocities determined from interplanetary scintillation (IPS) observations for 1973, a period when high-velocity streams were prevalent. The spacecraft and IPS velocities a

High resolution images obtained with the Arecibo radar system at a wavelength of 12.6 centimeters reveal numerous parallel 10- to 20-kilometer-wide bands of high radar backscatter situated on and oriented parallel to the major mountain ranges of the
